Microsoft’s MSDN blog is again offering a big batch of free technical ebooks, and this one is the largest collection to date.

Microsoft Senior Sales Excellence Manager Eric Ligman previously gave away 80 eBooks and then last summer 130 more. This collection includes some of last year’s favorites, but additional titles as well, such as Windows 10 for IT Professionals. There are some non-Microsoft-specific titles, such as the business-focused and sales titles shown above, as well as short PDFs showcasing keyboard shortcuts and quick setup guides. There might be something for everyone in this collection, so it’s worth a quick browse.
